Response time variability (RTV) is a useful measure of sustained attention; however, little is known about developmental changes in RTV at different temporal frequencies. Thirty-five 6-year-olds, 31 8-year-olds, and 37 10-year-olds completed the fixed-sequence Sustained Attention to Response Task on three occasions, six months apart. Fast Fourier Transform and ex-Gaussian analyses of response time (RT) data assessed momentary fluctuations in RT, gradual changes in RT, and very long responses, thought to reflect attentional control fluctuations, slow-shifting arousal, and infrequent lapses in attention, respectively. A half-by-half analysis measured within-occasion time-on-task effects. The 10-to 11-year-olds performed with less momentary fluctuations in RT, fewer long responses, and fewer commission and omission errors than the younger groups. This group performed well in the first half of the task but showed time-on-task effects on measures of momentary fluctuations in RT, very long responses, target sensitivity (d’), and commission errors. The 6- to 7-year-olds performed less well than the older groups, and showed time-on-task effects, on almost all measures. The 8- to- 9-year-olds mostly performed at an intermediate level compared with the other groups; however, this group performed with a similar level of momentary fluctuations in RT and very long responses as the 6- to 7-year-olds. These findings indicate that there is ongoing maturation of various aspects of sustained attention on a predictable task, with a period of relative stability in performance between 8 and 9 years of age. 相似文献

Patterning, or the ability to understand patterns, is a skill commonly taught to young children as part of school mathematics curricula. It seems likely that some aspects of executive function, such as cognitive flexibility, inhibition, and working memory, may be expressed in the patterning abilities of children. The primary objective of the present study was to examine the relationship between patterning and executive functioning for first grade children. In addition, the relations between patterning, executive functioning, mathematics, and reading were examined. The results showed that patterning was significantly related to cognitive flexibility and working memory, but not to inhibition. Patterning, cognitive flexibility, and working memory were significantly related to mathematical skills. Only patterning and working memory were significantly related to reading. Regression analyses and structural equation modeling both showed that patterning had effects on both reading and mathematics measures, and that the effects of cognitive flexibility were entirely mediated by patterning. Working memory had independent effects on reading and mathematics, and also effects moderated by patterning. In sum, these findings suggest that cognitive flexibility and working memory are related to patterning and express their effects on reading and mathematics in whole or in part through patterning. 相似文献

Simultaneous control of lower limb stepping movements and trunk motion is important for skilled walking; adapting gait to environmental constraints requires frequent alternations in stepping and trunk motion. These alterations provide a window into the locomotor strategies adopted by the walker. The authors examined gait strategies in young and healthy older adults when manipulating step width. Anteroposterior (AP) and mediolateral (ML) smoothness (quantified by harmonic ratios) and stepping consistency (quantified by gait variability) were analyzed during narrow and wide walking while controlling cadence to preferred pace. Results indicated older adults preserved ML smoothness at the expense of AP smoothness, shortened their steps, and exhibited reduced stepping consistency. The authors conclude that older adults prioritized ML control over forward progression during adaptive walking challenges. 相似文献

The Hebb repetition effect (Hebb, 1961) occurs when recall performance improves for a list that is repeated during a serial-recall task. This effect is considered a good experimental analogue to language learning. Our objective was to evaluate the role of overt language production in language learning by manipulating recall direction during a Hebb repetition paradigm. In each trial, seven nonsense syllables were presented auditorily. Participants had to orally recall the items either in the presentation order or in reverse order. One sequence was repeated every third trial. In Experiment 1, we compared learning from a group that had recalled the items in their presentation order to learning from a group that had recalled the items in the reverse order. The two groups yielded similar learning rates. In Experiment 2, recall direction was varied between trials. The learning rate was not affected when recall direction varied between trials, suggesting a limited role of overt language production in language learning. 相似文献

The intermediate psychological therapies service is provided for individuals referred with common mental health problems within the primary care psychological therapies service, but whose difficulties are longstanding and/or complex. The prevalence of borderline personality disorder (BPD) in intermediate psychological therapy services has not been researched to-date. The current study aimed to measure the prevalence of BPD amongst patients attending intermediate psychological therapies (n?=?63). The prevalence of BPD was established by identifying the number of patients who met DSM-IV criteria. BPD prevalence amongst patients attending an intermediate psychological therapy service was 37%. The high proportion of patients presenting with BPD indicates the potential need for staff training and supervision in how to manage such high levels of need at this service level. This is the first study to report prevalence rates of BPD specifically in an intermediate care psychological therapy service. 相似文献

Approximately 10% of Roman Catholic women seriously discern a vocation to religious life during their lifetime. Spiritual discernment is often characterized by prayer and spiritual direction, but also the acquisition of knowledge and information about religious life. No study to date has sought to understand how women seek out and retrieve information about religious life. Therefore, the current study sought to answer the following research question: “what is the information-seeking behavior (ISB) of Catholic women discerning a vocation to religious life?” using Dervin's Sense-Making Methodology. A survey was administered online and yielded responses from 124 participants. Findings indicated that digital and print resources were heavily utilized. However, participants indicated that connecting with a person face-to-face and visiting religious sisters produced a kind of knowledge and information that could not be acquired online, suggesting that their ISB was an integration of digital and print resources and human connection. This study contributes to the literature by intersecting the disciplines of information science and religion to equip practitioners who seek to develop resources for them. The study introduces the concept of limited Internet effectiveness in order to understand the integration of digital versus in-person resources in spiritual religious processes. 相似文献

Essentialist machismo practices, effectuated by masculine gender role socialization, help construct a mechanistic and limiting
male sexual ethos that exploits female sexuality in sexualized work environments. A critical site for exploring the intercrossing
of sexual and economic differentials is the cabaret—an intermediary of a strip club and a brothel—whereby males and females
utilize their financial assets and sexual appeal, respectively, to benefit and exploit each other. In this investigation,
we provide an understanding of the macro environmental contexts and micro intrapersonal and interpersonal factors that have
contributed to the historical evolution of the cabaret industry in the Greek-Cypriot Republic of Cyprus. Such industry has
evolved from a place of family entertainment to one of economic and sexual exploitation of Greek-Cypriot male cabaret patrons
and Eastern-European sex workers respectively. Various themes are explored, such as the limiting effects of patriarchal socializing
practices, male sexual anxiety, and sexual preoccupation. 相似文献

In this study we examined the division of finances, the division of household tasks, relationship maintenance behaviors, sexual activity, monogamy, and conflict among same-sex couples who had had civil unions in Vermont, same-sex couples who had not had civil unions recruited from their friendship circles, and married heterosexual couples recruited from among their siblings. Married heterosexuals had a more traditional, gendered division of finances, household tasks, and relationship maintenance behaviors, even though the heterosexuals were all siblings or in-laws of lesbians or gay men. Sexual orientation was a stronger predictor of the division of household tasks than was income difference within couples. Lesbians reported less frequent sexual activity than married heterosexual women, and gay men were less monogamous than married heterosexual men. Gay men in civil unions differed on a few variables from gay men not in civil unions, but there were no differences among lesbians. 相似文献
